SMOKING PIPE.

Application filed March 16, 1926. Serial No. 95,038.

An object of this invention is to provide an improved construction fortobacco or other smoking pipes wherein provision is made for eliminationfrom the smoke duct of saliva and the objectionable oils resulting fromcombustion.

A further object of this invention is to provide an improvedconstruction for tobacco or other smoking pipes wherein the smoke ductis interrupted intermediate of the pipe bowl and mouth-piece to precludepassage of the deleterious oils of combustion i'oin the bowl tothemouthpiece or of saliva from the mouth-piece to the bowl.

A further object of this invention is to provide means in a tobacco orother smoln ing pipe whereby saliva and the deleterious oils ofcombustion may be trapped before reaching the combustion chamber and themouth-piece respectively and conducted to a receptacle apart from thesmoke duct.

A further object of this invention is to provide means in a tobacco orother smoking pipe for deodorizing and neutralizing the fouling elementsgenerated within said pipe.

Another object of this invention is to provide an improved constructionfor a moisture trap adapted to be incorporated in a tobacco or othersmoking pipe.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which Figure 1 is a verticalsection of one form of pipe embodying my invention. Figure 2 is likewisea vertical section of another form of pipe embodying my invention.Figure 3 is a side elevation and Figure 4 an end view, on an enlargedscale, of the moisture trap comprising an essential part o1 myinvention.

In the construction of my improvement as shown, the numeral indicatesthe bowl or body portion of a pipe, said body portion being of anysuitable material and of any desired shape and contour and being provided with a combustion chamber or bowl 11, a stem portion 12, a bore 13within said stem, a smoke duct 1 1 connecting the bottom of the bowl 11with the bore 13, a cylindrical, downwardly-opening recess 15 beneathsaid bowl and separated therefrom and a passage connecting said recessand the bore 13, A mouth-piece 16, of any suitable material, is formedwith a smoke duct 17 throughout its length and forms a continuation ofthe stem 12, being removably and replaceably secured thereto in anydesired manner such as a friction slip-joint (Figure 1) or by means ofthreaded engagement (Figure 2). The end of the smoke duct 17 adjacentthe bore 13 is enlarged to form a cone or hell 18 opening into saidbore. A cup 19, preferably of metal or some other non-absorbingmaterial, is formed to fit the recess 15 and is mounted therein with itsopening downward and secured in some suitable manner to the body portionof the pipe. The rim of the cup 19 is internally threaded to engage withthreads on the edge of a closing plate 20, said plate being removableand replaceable to give access to the interior of the cup 19 at timesand being provided with a slotted boss 21, indented slot or other meansadapted for engagement by the edge of a coin, knife blade or the like tofacilitate rotation of said plate. A tube 22, preterably oinon-absorbing material, extends from an aperture in one side or cornerof the cup 19 through the passage between the recess 15 and bore 13 andterminates in an enlarged end or bell 23 adjacent to and registeringwith the bell 18 of the mouth-piece 16, said bell 28 being adapted toentirely fill and close the open end of the bore 13. A tube 2 1,likewise of non-absorbing mate rial and of less diameter than the tube22, is adapted to register at one end. with the smoke duct 14: and thusprovide a continuation of said duct, the other end of said tubeintersecting the bell 23, extending within said bell and registeringwith the smoke duct 17 of the mouth-piece 16 and spaced slightly fromsaid mouthpiece. The tubes 22 and 24: may be formed integrally or may bewelded, brazed, soldered or otherwise secured one to another in anymanner to seal the joint between said tubes and the lesser end of thetube 22 may be permanently sealed to the cup 19 or may fit snugly in anaperture formed for its reception in said cup. The space within the cup19 is preferably filled with absorptive material such as blotting paper,cotton or the like, to absorb and hold the liquids received in said cupand to prevent the return of said liquids through the tube 22 when thepipe is inverted or jarred. The absorptive material may conveniently beprepared in the form of a disc to be readily inserted in said cup andmay be treated with chemicals or solutions to deodorize or neutralizethe liquids absorbed thereby.

In the operation of my device, suction is applied to the end of themouth-piece 16 in a common manner and smoke is drawn from the burningcontents of the bowl 11 through the smoke duct 14 and. tube 24 to the,bell 23, thence through the smoke duct 17 tothe mouth of the smoker. Anyliquids or oils notin a gaseous state may be drawn with the smoke to theend of the tube 24 within the bell 23 where they are received by saidbell and pass along the tube 22 to the cup 19 and are absorbed and heldby the material within said cup. In like manner, any saliva which may beintroduced into the smoke duct 17 of the mouth-piece is prevented fromentering the tube 24 because of the spacing of said tube from said smokeduct, the saliva being diverted by the hell 1% into the bell 23 andthence through the tube 22 to the cup 19. Thus is provision made forcollecting and confining the liquids and oils which tend to foul a.smoking pipe, to the end that said pipe may be readily cleaned and mayat all times be sweet and unlouled. No attempt is made to filter thesmoke or to remove any of the products of combustion which are in agaseous condition, it not being here advanced that such an attempt wouldbe desirable.

It is easily apparent that my invention is adapted for use with varyingtypes of pipes of practically any shape or material and that slightstructural modifications may be made therein without departing from theprinciple of the invention, hence I do not wish to be limited to thespecific constructions illustrated but only by the scope of the appendedclaims.

I claim as my invention- 1. A smoking pipe comprising a body portionhaving a stem, a borei'n said stem, a bowl in said body portion, adownwardly-opening recess in said body portion beneath said bowl, spacedducts connecting said bowl and said recess with said bore, a removableand replaceable moisture trap within said bore comprising intersectingtubes adapted to register with said ducts and a mouth-piece fixed tosaid stem and formed with the convergent end of a duct adapted toregister with said trap.

A smoking pipe comprising a body por tion having a stem, a bowl in saidbody portion communicating with a bore in said stem. adownwardly-opening recess in said body portion beneath said bowl, areceptacle within said recess, a removable and replaceable cover on saidreceptacle, a tube formed with a bell-shaped end within said bore andcommunicating with said receptacle, a second tube intersecting andprojecting within the bell-shaped end of said first tube andcommunicating with said bowl and a mouth-piece engaging sa d stem andformed with a duct adapted to register with the bell-shaped end of saidfirst tube.

3. In a device 01": the character described, a body portion formed witha stem. a bowl and a downwardly-opening recess beneath said bowl, areceptacle within said recess, a moisture trap within said stemcommunicating with said bowl and receptacle, said trap comprisingintersecting tubes, one of said tubes projecting within the enlarged endof the other tube, together with a mouth-piece engaging said stem andformed with a duct adapted to register with said trap.
